Python修改Mp3文件名称
2010-03-26 00:00:00 来源:WEB开发网网上下载的很多mp3歌曲,都是用的时间ID比如20091003003.mp3这样的方式作为歌曲名称的,非常混乱!下载后,经常需要修改mp3的名字。这里我发一个我以前用Python写的,专门用来修改那些网上下载的mp3歌曲后名称不正确时候,使用该函数,使用方法
ModifyMp3FileInfo(r'E:\音乐\12345.mp3'),就是字典与列表的用法!代码如下:
#!修改下载的Mp3文件名称为正确的Mp3文件
def ModifyMp3FileInfo(filename):
mp3Id3V1 = {
"tag":{"valuepos":(0,3),"value":""},
"SongName":{"valuepos":(3,33),"value":""},
"SongPeople":{"valuepos":(33,63),"value":""},
"Zj":{"valuepos":(63,93),"value":""},
"Year":{"valuepos":(93,97),"value":""},
"Bak":{"valuepos":(97,125),"value":""}
}
try:
f = open(filename,'rb')
f.seek(-128,2)
sdata = f.read(3)
if sdata == 'TAG':
f.seek(-128,2)
sdata = f.read(128)
for tag,subitem in mp3Id3V1.items():
subitem["value"] = sdata[subitem["valuepos"][0]:subitem["valuepos"]
[1]].replace('\00','').strip()
print '%s='%tag,'%s'%subitem["value"],'\n'
f.close()
import os
if mp3Id3V1["SongName"]["value"]!='':
test = [os.path.dirname(filename),'\\']
test.append(mp3Id3V1["SongName"]["value"])
test.append('.mp3')
newfilename = ''.join(test)
print newfilename
if os.path.exists(newfilename):
test = ['Filename ',newfilename,' Has Existed']
print ''.join(test)
else:
try:
os.rename(filename,newfilename)
except WindowsError,e:
if e.winerror:
print 'Modify filename failed ,maybe the file is inuse'
else:
print 'UnKnown error'
else:
print 'Is not a MP3 file'
except IOError:
print 'Open file failed'
